8=384 9=248 hope this helped
5x + 4y = 32 ⇒ 45x + 36y = 288
9x - 1y = 33 ⇒ <u>45x - 5y = 165</u>
<u>41y</u> = <u>123</u>
41 41
y = 3
5x + 4(3) = 32
5x + 12 = 32
<u> - 12 - 12</u>
<u>5x</u> = <u>20</u>
5 5
x = 4
(x, y) = (4, 3)

Answer:
This is incomplete, but i will answer it in a general way.
A function is something like y = f(x)
You can think in a function like a "machine", that eats an input (x) and transforms it into an output (y).
The functions have a rule: For all the possible inputs, the function can transform them into only one output.
This means that if we have for an input x1.
f(x1) = y1 and f(x1) = y2
So f(x) maps x1 into two different values, y1 and y2, then this is not a function.
Now, you want to change the point (1, 4) of a relationship in order to transform it into a function (so in the relation R we have two points with x = 1, and differet values of y). Then you need to choose the option that in the x-component does not have the same value that one of the other data points of the relation.
Answer:
rate of change is
Step-by-step explanation:
first point is 45
second point is 90
45-90 subtract
45
